Paramontastraea
Paramontastraea is a genus of stony corals in the family Montastraeidae. The genus is characterized by its distinctive morphology, which includes a robust corallum with a prominent columella. These corals are found in a variety of tropical and subtropical marine environments, playing an important role in reef ecosystems.
Common Names
Common names for species within the genus Paramontastraea include "pillar coral" and "branching coral." These names are derived from the characteristic growth forms of many species.
Characteristics
Paramontastraea corals exhibit several key characteristics:
- Robust Corallum: The skeleton of Paramontastraea is generally thick and strong, providing structural support for the colony.
- Prominent Columella: The center of the corallite, known as the columella, is often well-developed and prominent, contributing to the distinctive morphology of the genus.
- Branching or Columnar Growth Forms: Species within Paramontastraea display various growth forms, including branching, columnar, and massive colonies.
- Zooxanthellae: Like many stony corals, Paramontastraea species host symbiotic zooxanthellae, single-celled algae that provide the coral with energy through photosynthesis.
Environments
Paramontastraea corals are typically found in shallow, tropical and subtropical marine environments. They thrive in clear, well-lit waters and are often associated with coral reefs. These corals are known to be tolerant of moderate wave action and currents.
